History of the State of New York, Vol. I (1609-1691)
A very extensive tract of country was also purchased from the Natives, being Mahikanders, 36 leagues up the North river, where Fort Orange was founded on behalf of the Company, and afterwards the Colonic of Renselaerswyk. From the Southern Indians a large tract of land, called Swanendaal, was purchased on the West sliore of the South bay, not far from Cape Hindlopen, and taken possession of by the building of a small fort, where 28 men were, one day, treacherously murdered by the Indians. On the East bank of the South river is built Fort Nassau, and on the West bank, the Redoubt Beversreede, situate at the Schuylkil. These above described lands, forts and rivers were taken possession of, inhabited, built, traded at and frequented on the account of the abovementioned Company, and the same is continued up to this date. In the year 1633, Wolter van Twiller, at the time Director in New Netherland, purchased the territory called Conittekock, situate on the Fresh River of New Netherland, long before any other Christian Nation had been there. Van Twiller, immediately after the sale, payment and conveyance, caused possession to be taken of that land, and there for the account of the Company had Fort Hope built, which is continually to this date occupied by a garrison who also made a bouvverie there and cultivated the soil.

HOLLAND DOCUMENTS : VII. 543 This aforesaid land, called by the Natives Conitte kock, lies about 20 to 21 lengues up the river, being situate in the jurisdiction of the Chief Sequeen, which Chief or Sakima was, in his time, Lord and right owner of the entire river and the lands thereabouts. But inasmuch as a difficulty arose between the Chief of the Pequatoos, named Meantioni and the Sequeen, respecting the jurisdiction and propriety of said river, these Sakimas or Chiefs agreed to meet and fight in the field, each with his entire force, on condition that whoso remained conqueror should, himself and his successors be and remain forever.
